Polymers are molecules of high molecular mass formed by joining together large numbers of small molecules, called monomers. There are two general methods of creating polymers. In addition polymerization, monomers couple through the opening of their multiple bonds, as seen in the formation of polyethylene.(FigureJ.) In condensation polymerization, two monomers join by the elimination of a small molecule such as water as seen in...

Which type of polymerization involves the loss of a small molecule during the polymerization reactions? a) subtraction polymerization b) sequential polymerization c) addition polymerization d) condensation polymerization What is one of the most common ways that the properties of a polymer can be altered?

i) Which of the following is not true about step-growth polymers? Formation of step-growth polymers usually results in the loss of a small molecule. Step-growth polymers are formed by the reaction of bifunctional molecules. Step-growth polymers can be formed by a free radical mechanism. Step-growth polymers are also known as condensation polymers. Step-growth polymers do not reach high molecular weight until the reaction has gone nearly to completion. ii) Which of the following are not termination methods in radical polymerization?...

Which of the following statements about enzymes are true? Select all that apply: Enzymes increase reaction rates by lowering the energy of the products. Enzymes increase the rate at which products are created by preventing reactions from running backwards. Enzymes increase reaction rates by lowering the activation energy of a reaction. Enzymes increase reaction rates by interacting with the substrate molecules to facilitate the reaction, for example by contorting them to facilitate bond-breakage or orienting them to favor bond formation.

Which of the following statements about the Aldol reaction is correct. Select all that apply. The aldol condensation reaction requires only a catalytic amount of base to form the a, -unsaturated carbonyl product In an Aldol reaction, the enolate is the electrophile that reacts with a neutral carbonyl nucleophile. Reacting 1 equivalent of LDA (lithium diisopropylamide) with 3-pentanone, the enolate will be formed quantitatively. Two equivalents of a ketone can be reacted with NaOH to form a B-hydroxycarbonyl product. Aldol...
Which of the following statements about IR spectroscopy are true? Check all that apply. The frequency...
Which of the following statements about IR spectroscopy are true? Check all that apply. The frequency of vibration depends on the mass of the atoms on either end of the excited bond. A common light source used to generate light of IR wavelengths is a tungsten filament lamp. The type of bond (single, double, triple) has no effect on the energy required for excitation in IR spectroscopy. The potential energy of bond oscillation is affected by Coulombic repulsion when the...
